This makes it difficult to update an application which works
with other DLM's as all the completion AST routines need to be
updated to test for EUNLOCK to figure out why they've been
invoked.

Would it be possible to add an optional argument to dlm_unlock()
for the AST routine to call when the unlock completes?
If this is omitted, the existing completion AST routine is
executed.
